HOLDBACK FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 406,043, dated July 2, 1889.

Application tiled October 2, 1888.

T0 all whom it may concern:

Be it known that I, JOHN B. HAIN, of Edgerton, in the county of Rock and. State of lVisconsin, have invented new and useful Improvements in Holdback Attachments for Vehicles; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accolnpanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in holdback straps and irons for single carriages, and pertains to the construction of the holdback-iron and the combination and arrangement of the holdback-iron with the thill, the holdback and thill-supporting straps.

The construction of my invention is explained by reference to the accompanying drawings, in which- Figure l represents a side view of my invention as shown upon one side of the vehicle, a duplicate of the same being shown upon the opposite side. Fig. 2 represents a lengt tudinal section of the holdback-iron removed from the thill. Fig. represents a top view of the iron shown in Fig. 2. Fig. I is a detail showing the manner of connecting the holdbackstrap with the thill-supporting strap.

The holdback-iron consists of the plate A, the downward and forward projecting straphook B, which is riveted or otherwise rigidly secured to the plate A, the swinging arm or keeper C, which is pivoted to the plate A by trunnions D D,operating in the recesses E E, formed therefor in the upper side of the plate A, and spring F, which is secured to the upper surface of the plate A within the chamber G by a retainingrivet Il. The chamber Gr is formed for the reception of both the spring F and the pivoted end of the keeper C, whereby the required space is provided for the movements of the spring and keeper. The spring F may be formed of a single plate, but is preferably formed of two thin plates arranged parallel to and in close contact with each other. The object of using two plates instead of one is to attain greater elasticity and strength, with less liabilityY of the spring being broken than would be the Serial No. 286,973. (No model.)

case with a single spring of equal heft. The pivoted end of the arm or keeper C is provided with a spring-retaining notch or recess d for the reception of the bearing end of the spring, whereby said keeper C is retained in contact with the lower end of the strap-hook B. A small recess or aperture l) is formed in the lower end of the keeper C for the reception of the stud d, formed on the lower end of the strap -hook B, whereby, when said keeper C is in a closed position, said stud (l resists all such side or lateral strain as may be brought to bear upon the swinging end of said keeper, whereby the strain, which would otherwise be brought to bear upon the pivots D D, is prevented.

I is a shoulder formed on the front side of the retaining-keeper C, and serves as a stop to said keeper in its forward movement as the holdba-ck-strap is being withdrawn from the strap-hook B.

J is the holdback-strap, which .is connected at its rear end with the rear part ot' the harness in the ordinary manner, and its front end engages upon the strap-hook l.

K is the ordinary thill-strap of the harness by which the front end of the thill is sup ported.

To provide for disengaging the holdback strap J from the hook B automatically when the horse is unhitched and led forward, I have connected the front end of the hOldback-strap J with the thill-strap K by a connecting-st rap I., wherebyit is obvious that, the traces of the harness being disengaged and the horse boing led forward, the front end of the hold` back-strap J will be drawn downward and forward by said strap L and disengaged from the hook l5. The rear end of the strap I. is provided with a buckle M, which engages or buckles into the inner fold ol' the holdbaekstrap J at a slight distance in rear of the strap hook 13, as shown in Fig. 4, whereby said strap L is prevented from becoming entangled with or getting in front of the strap-hook. I3.

lIavin g thus described my invention, what I claim as new, and desire to secure by Let-ters Patent, is

The combination of the thill Il with the holdback attachment, consisting of the plate A, keeper-retaining springs F, and keeper C, In testimony whereof I afxlny signature in 1o with Jche holdbaek-strap J, chill-strap K, and presence of two Witnesses. connecting-strap L, said holdbaGk-strap J being connected at its front end with the stmp- JOHN B. HAIN. 5 hook B and at its rem' end with the rear part of the harness, said strap L being Connected XVfnnesses: at its rear end with said strap J and at its JOHN SPENCER, front end with said holdback-strap K, all Sub- EMEROY MAIN. stantially as and for the purpose specified.
